Arthur S Buddy Bland, Rita Buzzi Rausch · CERN Document Server (European Organization for Nuclear Research) · 1990
An overview of the LEP controls architecture and a description of the communication and equipment networks are given.The distributed architecture makes use of 57 process computers and 40 consoles located in the LEP underground and surface buildings.The control of all LEP equipment is achieved by 8 and 16 bit microprocessor assemblies driven by real-time kernels and languages.The paper presents in some detail the control of the large variety of LEP equiment including industrial turn-key systems.Particular emphasis will be made to the equipment controls protocol.
